## Easy to use
|
|
|
|
To use the std::vector implementation for specified type they should be declared as follows:
|
|
|
|
```C
|
|
#define CVEC_TYPE TypeOfVectorElement
|
|
#include "cvec.h"
|
|
|
|
// ...
|
|
|
|
TypeOfVectorElement *vec = cvec_TypeOfVectorElement_new(128);
|
|
|
|
cvec_TypeOfVectorElement_push_back(&vec, value);
|
|
```
|
|
|
|
Also somewhere in the project the functinos should be instantiated as follows:
|
|
|
|
```C
|
|
#define CVEC_TYPE TypeOfVectorElement
|
|
#define CVEC_INST
|
|
#include "cvec.h"
|
|
```
|
|
|
|
## Allows using of custom allocators.
|
|
|
|
```C
|
|
#define CVEC_TYPE pchar
|
|
#define CVEC_INST
|
|
#define CVEC_MALLOC custom_malloc
|
|
#define CVEC_REALLOC custom_realloc
|
|
#define CVEC_FREE custom_free
|
|
#include "cvec.h"
|
|
```
|
|
|
|
## Allows handling of exceptional cases.
|
|
|
|
```C
|
|
#define CVEC_TYPE pchar
|
|
#define CVEC_INST
|
|
// Set Out Of Bounds handler
|
|
#define CVEC_OOBH(funcname, vec, index) printf("Out of bounds in %s (vec = %p, i = %d)", funcname, vec, index); abort();
|
|
#include "cvec.h"
|
|
```
|
|
|
|
## Has no fixed dependencies
|
|
|
|
Every function it uses may be overridden. More information about dependencies in [cvec.h](cvec.h).
